Online persona

I think that my online persona is going to be named Cally. I would like her to be younger than me, maybe a senior in high school. I would also like her to be an aspiring writer. I think the things that she is going to write are going to be short works of fiction. Little scenes and maybe a couple of medium sized stories. She lives in New Orleans so most of her writing ends up having a ghost or a creature in it. She lives with her mother and her older brother and so she adds a lot of heroes into her stories that sound like him. She is home schooled because her mother doesn't see the point in putting her through the public school system in New Orleans.
